GASEOUS FUEL.

80 Drawing. I

which the following is a full, clear, and

exact description...

This invention relates to gaseous fuels, and more particularly to a gaseous fuel which, when used in combination with oxygen, is especially adapted for the purpose of cuttin r metals.

It is the general object of the invention to produce a gaseous fuel which is relatively inexpensive, which will enable the cutting operation to be performed in a most eflicient manner, and with the use of a gas which is ordinarily readily obtainable.

I prepare a gaseous fuel by which the foregoing general object may be realized by saturating or impregnating carbon mouoxide with ordinary commercial ether. The most convenient manner in which this saturation or impregnation may be accomplished is by introducing into a cylinder containing about 200 cu. ft. of carbon monoxide, from one to two pounds of commercial ether. When the delivery valve' from such a tank is opened, the carbon monoxide, impregpated with the ether, will be supplied to the lowpipe and tlie'latter may be operated with oxygen in the usual manner.

When the ether is. added to and mixed with the carbon monoxide in the manner set forth hereinbefore, the resultant gageous' fuel will consist of approximately 97% to 95 parts by volume of such gas, to approximately 2 to 5 parts by volume of ether vapor.

The advantage of my fuel mixture is that the ether increases the-flame temperature. and the heat units of the carbon monoxide. Furthermore, by reason of the fact that it lowers the igniting point of the carbon monoxide, the mixture can be used with ordinary blowpipe tips, without danger of the flame being blown oil such tips, as is the case where carbon monoxide is attempted to be used without dilution with such heavier hydrocarbon-ears then tips intended for Application filed December 6, 1923. Serial in. 678,809.

burning carbon'monoxide have to be provided with special cups for the prevention of this blowing out or blowing oif of the preheating flame.

By the use of my invention, the carbon monoxide can now be used with the same facility as ordinary cutting gases, but at much less cost and with greater eificiency.

Where one pound of ether is employed with a cylinder of gas, the resultant gas .will realize all of the advantages set forth 'hereinbefore; where two pounds of ether are employed with a cylinder of gas, a corresponding increase in flame temperature and heat units will be realized, with a corresponding increase in the speed of cutting, and the igniting point will be further lowered, thus insuring the maintenance of the flame at the blowpipetips without liability of being blown off. Furthermore, with the higher limit or larger quantity of other, the

gas is particularly useful for cutting heavy masses of metal or dirty metal with great facility.

While commercial or ethyl ether is preferred for admixture with carbon monoxide,

because of its richness in carbon and hydrogcn, my invention contemplates the use of methyl ether, as well, for such admixture.

Having thus described my invention, what I claim is:

1. A aseous fuel particularly useful for the cutting of metal and consisting essentially of a mixture of carbon monoxide with the "apor of ether in the proportions of from not materiall less than 2 to not materially more t ian 5 parts by volume of the ether vapor, to from not'materially more than 97 to not materially'less than 95 parts by volume 'of the carbon monoxide.

' 2. A cutting gas consisting essentially of carbon monoxide having mixed therewith vapor of ether, the ether vapor constituting not materially less than 2 71, by volume of the mixture and the carbon monoxide constituting not materially more than 9714:); by volume of the mixture.

In testimony whereof, I hereunto affix my signature.

JOHN HARRIS.
